53 * Virtual address space layout:
54 * -----------------------------
55 * 0x0000_0000 - 0xbfff_ffff : user process
57 * 0xc040_0000 - virtual_avail : kernel reserved (text, data, page tables
58 * : structures, ARM stacks etc.)
59 * virtual_avail - 0xefff_ffff : KVA (virtual_avail is typically < 0xc0a0_0000)
60 * 0xf000_0000 - 0xf0ff_ffff : no-cache allocation area (16MB)
61 * 0xf100_0000 - 0xf10f_ffff : SoC integrated devices registers range (1MB)
62 * 0xf110_0000 - 0xf11f_ffff : PCI-Express I/O space (1MB)
63 * 0xf120_0000 - 0xf12f_ffff : unused (1MB)
64 * 0xf130_0000 - 0xf52f_ffff : PCI-Express memory space (64MB)
65 * 0xf930_0000 - 0xfffe_ffff : unused (~172MB)
66 * 0xffff_0000 - 0xffff_0fff : 'high' vectors page (4KB)
67 * 0xffff_1000 - 0xffff_1fff : ARM_TP_ADDRESS/RAS page (4KB)
68 * 0xffff_2000 - 0xffff_ffff : unused (~55KB)
